The introduction of pasteurization helped eliminate this problem. bovis infection was recognised as a major public health problem when this organism was transmitted to man via milk from infected cows. bovis infections in man and a variety of animal species are reviewed. The factors determining susceptibility to infection and clinical disease, and the infectiousness of infected hosts and transmission of infection, are detailed. bovis strains as an epidemiological tool and of BCG vaccination of humans and cattle as a control measure are reviewed. The usefulness of DNA fingerprinting of M. Possible methods of limiting spread of infection from wildlife to cattle including the use of vaccines are outlined. In countries where there is transmission of infection from endemically infected wildlife populations to cattle or other farmed animals, eradication is not feasible and control measures must be applied indefinitely. Many susceptible species, including man, are spillover hosts in which infection is not self-maintaining. Susceptible species include cattle, humans, non-human primates, goats, cats, dogs, pigs, buffalo, badgers, possums, deer and bison. Mycobacterium bovis, the cause of bovine-type tuberculosis, has an exceptionally wide host range. Tuberculosis is primarily a respiratory disease and transmission of infection within and between species is mainly by the airborne route.
